To aZZ whom it may concern ARTHUR, O. HUBBARD,

Be itknown that l a citizen of theUnitedStates, resident of.

Minneapolis, county of Hennepin', State of Minnesota, have: invented certain new and useful Improvements in Folding Boxes," of

The object of my invention isto provide a folding box .of stronger andv more durable construction, though correspondingin general appearance and manner offoldingto the box shown and described in Letters ,Patentof the United: States, issued t0-1ne-onthe 28th day ofJune, 1898, No. 606,459.

Other objectsof the invention will. appear. from the followingdetailed description. 1 I

i The invention consists: generally in variousconstructions and c'ombmations, all as ed out in the claims;

hereinafter described and particularly point In the accompany Figure l-is a perspective view ofa folding box embodying my. invention, 1

of the box, composed of thin panel-like material arranged in strips, running lengthwise of the box and placed edge to edge-from the bottomto the top. 3 and 4; are top and bottom rails, made of thicker, heavier material and 5 and 6 are t-he end"railsyhaving tenons at the ends fitting mortises in the ends of the top and bottom rails. panels 2 top rails 3 and bottom rails P and are alsoequipped with vertical end rails 5 and 6 mortised to the top and bottom rails. The side and end Walls are pierced vertically toreceive reinforcing'and bracing wires 7 which are bent so that their ends are in parallel relation and pass down through the top rails and upon opposite sides of the panels 2, the lower ends of the wires penetrating the bottom rails to a point near the bottom ng drawings forming; .partof this specification,-;

The end walls have and having their ends outwardly turned and locked in therails.

These wires 7 not only hold the panels with their edges in alignment, but unite the upper and lower rails of the" box and prevent thepanels from working out of the glfOOVGSJIr the end rails." "Loops 8 are pro- *VlClBd, herein shown as fitting between the abutting longitudinal edges of the panels for holding the ends of the wires in parallel relation and clamping them firmly against the faces; of the panels. It will be understood, however, that these loops are placed by a machine equi-distant apart and some of themmay be in the joints between the sections of the panels, as shown, but some of them: maybe mounted in the sections of the panels themselves. The function, how

ever, of theloops is. the same in-both'cases. The panels are thereby heldsecurely against sliding or slipping,either vertically or horizontally, and at the same time are free to yield slightly under pressure-and are therefore inless danger of being broken. when handled roughly or when the box is heavily loaded. The ends ofthe panels are seated in grooves provided in the upright rails."

The loops 8 are preferably formed of wire that is-inserted between or through the sections of the panels andbent around the reinforcing wires, as indicated in Figure 3,

to form an eye or loop." The side and end walls are of substantiallv the same structure .asfar as reinforcing is concerned and the description above will sufficefor both walls g iofthe box. In the drawing, Q repre'sentsthe side walls For connecting theiside' and end walls I prefer toex'nploy the following construc- .tion.

7 9 and 9 represent metallic strips, folded into .U-shape formfand fitting the endsof the walls at the top and bottom ing their ends inserted through holes 13 in the rounded portion of the straps and then folded or bent to lie on the inner surface of the straps and lock the staple therein. These staples are so arranged that their 100p portions will lie in different planes substantially at right angles to one another and permit freedom of movement of the walls one upon the other. The diagonally opposite rails 6 of the sidewalls have offsets 6 therein and straps 9 are fashioned to fit these offsets so that when the box is folded a space will be formed between the opposite side and end walls to receive the bottom plate 14 that is hinged to one of the side walls and is free to drop down to a horizontal position between the walls and close the bottom when the box is unfolded or set up.

As compared with the box of my former patent, above referred to, it will be noted that substantially horizontal and upright rails are provided at the top and bottom and the corners of the box, the joints connecting these rails being strengthened by metallic reinforcement, while the panels between the rails are braced and strengthened by the vertically arranged reinforcing wires. A box of this'construction is therefore stronger and more durable than the one described in my former patent while the general principle of folding and hinging the bottom of the box is embodied in both constructions.

I claim as my invention:

l. A folding box comprising side and end walls, each wall composed of top and bottom .and end railssecured together and an intermediate panel of comparatively thin material and made up of a plurality of narrow strips placed edge to edge, reinforcing wires passing vertically through the top and bottom rails and upon opposite sides of said panel strips, and loops connecting the wires onopposite sides of the panel.

2. A; folding box comprising side and end-walls having upper and lower and end rails mortised together, a panel composed of comparatively thin narrow strips fitting between said upper and lower and end rails, reinforcing wires bent to form loops inserted vertically through said upper and lower rails upon opposite sides of said strips, the lower ends of the wires being locked in the lower rails and wire loops connecting at intervals the opposite portions of the wires through the walls of the box.

3. A folding box, comprising side and end walls having upper and lower horizontal rails and vertical end rails between them, metallic strips, U-shaped in form, fitting the ends of said walls and bridging the joints between the upper and lower and end rails and secured to said rails, and staples having their end portions mounted in said strips and their looped portions intermediate to form a hinged connecting means between the opposite strips.

l. A folding box comprising side and end walls having upper and lower rails and U-shaped straps fitting the ends of said walls and secured thereto and bridging the joints between the end rails and said upper and lower rails, and hinge connections be of comparatively thin material placed edge to edge, reinforcing wires passing vertically through holes in said top and bottom rails upon opposite sides of said panels and" seated snugly against the surfaces of said panels, and loops passed around said wires and. extending through the joints between said strips and connecting the wires on one side of said panel with the corresponding wires on the opposite side.

6. A box comprising side and end walls having upper and lower and end rails secured together, a panel composed of strips of thinner material than saidend rails placed edge to edge with the ends of said strips seated w1th1n vertical grooves in the end rails of said walls, 're nforcing wires passing vertically through said top and bottom rails upon opposite sides of said panel strips ARTHUR o.
